The 202 has the reference 20 preamp and the 305/7 have the reference 30 preamp already in the receiver.
If you are not happy with the sound quality or power ect then you plug in an aftemarket 5/6 channel amp of your choice and you have your seperates.
Down the road the receiver will probably sell for more than the seperate processor.
